Privacy has become one of the key pieces of digital communication, although it is increasingly common to see situations in which people are not aware of what they share. This is especially relevant in messaging applications, such as WhatsApp, the key element of digital communication in Spainwith friends, co-workers, companies and strangers.

That is why knowing how to use this service is especially important, especially for the little ones, although In theory, children under 16 years of age should not be given access to this app.. However, even adults sometimes err on the side of being too trusting, and leave their unlocked cell phone within the reach of strangers.

To prevent that person from having access to the conversations we have had on WhatsApp It is a good idea to secure the application by using our fingerprint. In this way, we will be asked to use it every time we enter the application. Obviously, this feature is very easy to activate and deactivate, in case you do not want to have it on permanently.

How to use fingerprint on WhatsApp

This feature comes standard in the app and It is compatible with all current Android phones that have a fingerprint sensor, whether on the screen, on the back or on the side. To activate the function you must open WhatsApp, click on the three vertical dots button in the upper right corner and enter the section Settings.

Once there you have to go to the part of Privacy, where you have to slide on the screen to the end, where there is a section called Lock with fingerprint. When you enter you can activate this function, for which you will be asked to use your own fingerprint.

Once the function is activated can be set to lock immediately when closing the application, after 1 minute or after 30 minutes. In this way, you can choose the most convenient way for each person, without it being particularly uncomfortable to have this function activated. Additionally, it can be configured so that notifications do not show the content, increasing security. From that moment on, the app will only open when we put one of the registered fingerprints on the mobile.
